Having problems recording...

[KiraSTRIKE]

Hi. Whenever I am playing Medal of Honor: Warfighter and decided to record it with Action! it seems it would only be able to record the video itself in-game - yet it doesn't record the audio in-game. Am I doing something wrong? What's odd though is that I have tried playing other games such as Hawken and it would be able to record both the audio and video whatsoever.

Do you have any additional sound card?
